Paths must be fully qualified

Error message

Paths must be fully qualified

What it means

Puppet::FileServing::Base#path= stores a file-serving object's base path and requires it to be absolute, checked with Puppet::FileServing::Base.absolute? (POSIX leading-slash, or drive/UNC form when running on Windows). Any relative path raises ArgumentError. This setter underpins fileserver.conf mounts and metadata construction, so mount points and similar inputs must be absolute.

Solutions

1. Use an absolute path in the mount: `path = /etc/puppetlabs/code/environments/$environment/files/extra`
2. On Windows use drive-letter (C:\...) or UNC (\\server\share\...) absolute paths
3. When building paths in Ruby, anchor them: File.expand_path(p) or root.join(p)

Example fix

# fileserver.conf — before
[extra_files]
  path files/extra
# after
[extra_files]
  path /etc/puppetlabs/code/environments/$environment/files/extra

def mount_path_ok?(p)
  Puppet::Util.absolute_path?(p, :posix) || (Puppet::Util::Platform.windows? && Puppet::Util.absolute_path?(p, :windows))
end
raise ArgumentError, "mount path must be absolute: #{p}" unless mount_path_ok?(p)

def absolute_mount?(p)
  p.is_a?(String) && p.start_with?('/') || p.match?(/\A[a-zA-Z]:[\\\/]/) || p.start_with?('\\\\')
end

When it happens

Trigger: A fileserver.conf mount whose path is relative (`[extra_files]` + `path files/extra`); Ruby code assigning a relative path to a FileServing object; interpolating a relative setting value into path=.

Common situations: Assuming paths resolve relative to puppet.conf or the environment directory; configs ported from tools where relative paths were allowed.
